Note

It is important to make a note of the IPEI code. The IPEI code may be needed

Getting started 10

When using the cordless phone for the first time, follow the steps below to

prepare the cordless phone.

Warnings

• Do not use the equipment in conditions where there is a danger of electri-

cally ignited explosions.

• Do not expose the equipment to direct sunlight for long periods.

• Keep the equipment away from excessive heat and moisture.

• Make sure the local mains voltage corresponds to the voltage on the

Note

Only use the charger that comes with the cordless phone.

PREPARING FOR USE

Getting started 11

1. Attach the clip to the cordless phone. Do not press on the display!

2. Place the battery as shown below. Make sure that the battery wires are

put through the notches as shown.

Getting started 12

Getting started 13

3. Connect the mains adapter to the charger and connect it to the mains out-

let.

If you place the charger on a wall, screw the wall mount to the wall.

4. Place the cordless phone in the charger to charge the battery.

Getting started 14

Complete charging before you subscribe or use the cordless phone. The

green light of the charger is turned off when charging is completed. For more

information about charging the battery, please refer to “Battery” on page 15.

Getting started 15

5. Subscribe the cordless phone to the telephone network. Follow the proce-

dure in “Subscribing to a network” on page 97.

When the cordless phone is subscribed to a telephone network, the cordless

phone is ready for use. See also “Telephone networking in short” on page 34.

The cordless phone is powered by a rechargeable battery. You can fully

charge a flat battery by placing the cordless phone in the charger for 3 hours.

A fully charged battery gives you up to 15 hours calling time or up to 150

hours stand-by time. The cordless phone has a battery meter, which indicates

the power left in the battery.

Note

The cordless phone is powered by a Nickel Metal Hydride (NiMH) battery. It

can be recharged at any time. To keep the battery fully charged, you can put

or leave the cordless phone in the charger without any problem.

BATTERY

Getting started 16

Reading the battery meter

When the battery is fully charged, the battery meter on the cordless phone

display consists of four blocks. The number of blocks decreases as the bat-

tery discharges. If the battery is almost flat, the battery meter and the red light

on the cordless phone flash. An alarm sounds if there is less than 15 minutes

calling time left in the battery.

Charging the battery

Place the cordless phone in the charger as shown in the picture below.

Getting started 17

If the lower green light on the charger is on (and the battery meter on the dis-

play flashes), the battery in the cordless phone is being charged. As soon as

the battery is fully charged, the lower green light is turned off and the battery

meter on the cordless phone stops flashing.

Getting started 18

If the battery is completely flat it can take a few minutes before the lower

green light on the charger comes on.

Changing the battery

Rechargeable batteries have a limited lifespan.

If the stand-by time for the cordless phone becomes too low, you should

replace the battery. Please contact your system manager or supplier for more

information.

Warning

Only use batteries as specified in “Technical specifications” on page 127.

The battery does not contain cadmium and is therefore more environmentally-

friendly than other rechargeable batteries. However, all batteries should be

treated as chemical waste.

Getting started 19

The cordless phone has a clip to attach the cordless phone to your clothes.

• How to attach the clip to the cordless phone: see “Preparing for use” on

page 10 for specific instructions.

• How to remove the clip from the cordless phone: see the drawing below.

Note

To minimize wear and tear, we recommend that you do not remove the clip

from the cordless phone too often.
